Patent DE-19507702-C1 (DE)
Title: In=situ pipeline replacement method
IPC: F16L55/165
Filed: 1995-03-04
Granted: 1996-04-25
Abstract: The method described requires no excavation but uses a soil-displacement technique. It calls for the old pipe to be pushed outwards from the inside in a controlled fashion, working from the existing inspection shafts. The new pipe, e.g. of plastic, is produced in situ, e.g. by injection moulding. The old pipe is widened only by the amount necessary for the walls of the new pipe to be made thick enough to withstand the forces to which it will be subjected. Provided that account is taken of the surroundings of the existing pipe (e.g. the proximity of other pipes, anchorage points, etc.), the method can be used, within limits, to correct deformations in the pipe trajectory. The method can be used both to renew short lengths of pipe (e.g. as part of a repair programme) and also to renew whole networks. One of the advantages of the method is that the internal diameter of the new pipe is at least as great as that of the original pipe, thus preventing the formation of constrictions.

Abstract: The converter includes a number of input latch gates formed as current sources (EL/SQ1, ... EL/SQi, ... EL/SPm) which are connected with parallel inputs (Al, ... Ai, ... Am) at an input, and with a signal bus conductor (BL) at an output side. The input latch gates are activated individually through a selection arrangement (SR) pulsed with a clock signal (CLK).  An evaluation unit (BW) is connected at an input with the signal bus conductor (BL) and at an output (K4) with an output latch gate (LOUT), to form a serial output signal (B).  A reference input latch gate (REL/RSQ) is provided as a current source, and is activated every time simultaneously with one of the input latch gates. The reference input latch gate is connected at an output over a reference bus conductor (RBL) with a reference evaluation unit (RBW), whereby the reference bus conductor comprises always a larger signal time width than the time width of the signal bus conductor. A ready signal (RDY) is produced from the output signal of the reference evaluation unit, and an activation signal (EN) is formed in an unit (TBUF) from the ready signal and the clock signal. The activation signal is supplied as a load signal to the output latch gate.

The exchange module (16) transmits the read event information over the data transmission path to the main processor. The exchange module blocks accessibility on the temporary memory of a certain terminal on arrival of new event information from the terminal if the exchange module did not receive a corresponding feedback about the processing of an earlier event information from the main processor arrangement.
